Fatimah

We have known from our childhood that our holy prophet (sws) had four daughters including Hazrat Fatima, Hazrat Um-e-Kulsoon, Hazrat Ruqaeeya and fourth one I am not sure Hazrat zainab (RA), but recently through one of my shia colleague I got to know that they have the faith that our Prophet had only one daughter Hazrat Fatima (RA). Can you refer to me the Ahadith from Sihah about correct numbers of their family members?
